In many projects, YouTube videos are embedded and there is a need to display these images in grid view. For displaying videos in grid view, we have to create another view for thumbnail view, create objects for this view and add it to the main view. However, I have a simpler and effective solution for this: Sample Project for YouTubes in GridView: Detail: I am using following classes: —SampleProjMoreVideosController.h and —CustomCell.h and CustomCell.m Two Nib files: — SampleProjMoreVideosController.xib: — CustomCell.xib: Logic: I have used table view and custom table view cell.In custom table view cell ,I have placed three web views and embedding the YouTube videos. CustomCell.h: |
